Yes, what Brad said. We just show up with a bunch of 996's to a track day and have a great time. Be warned that Brad and Aaron are pretty serious about this and are really fast drivers.
I am heading out to Lime Rock on April 25th with Track Night in America, weather permitting.

 

Thank you. I will try to swing by for the 996 event. That sounds pretty cool.

 

What is are the differences between 996.1 MT C2 vs C4 and eGas vs cable throttle? Seems like they should be minor.

 

If you run the UIDS and the UAOS with the track drain, what's the recommended capacity total? Just want to confirm

No difference between 996.1 C2 and C4.....All 996.1 are the same kit except the 99C2 w/cable TB ....it takes a different kit ..

 

Recommended oil fill for Track work
UIDS alone .......9.9qts w/filter ...Note:On any m96/7 engines
UIDS with UAOS Track Version ....10.9 qts w/filter
UIDS with UAOS Track Version and less than 80 LPM as measured by this technique https://rennlist.com/forums/996-foru...=Engine+health ....11.9 qts w/filter

 

Don't know if anyone caught the significance of being able to handle running 1 qt more oil over full using the UAOS Track version in Skips post on the UIDS.

AND, if you pass Skips blow by test, you may be able to run 2qts over full. That's significant.

From experience I can tell you that the OEM AOS cannot handle running full oil (9.9). Forget about 1 qt over full (10.9). The Porsche Motorsports AOS can handle running full oil (9.9), but it cannot handle running 1 qt over full (10.9).

So with an engine that passes Skips blow by test, you can run 11.9. Cool. Very cool. Nice work Skip.

 

Well, running 20% more oil and the thermal properties of that must be amazing. So much more volume to have to get hot when on the track would be a really good thing!

 

Yeah, the M96 likes lots of cool oil. Prevents alot of issues we don't want.

 

Thanks !!

 

I have a UAOS with Track Duty Auto-Drain installed on my '01 Supercharged C2. The car runs perfectly, but when I drive it hard, it experiences excessive crankcase pressure, causing oil to leak from the oil fill cap/vent valve on the valve cover. Has anyone installed this oil separator/catch can on a supercharged car? If so, have you had the same experience? How can I fix it, or should I remove the UAOS?

 

Any thoughts on what this residue is that wipes off the drain plug of the UAOS reservoir? I’ve had the UAOS installed for a year and a half and I never have any oil in the reservoir, just this orangey-brown dried residue on the plug. 1999 C2 with 111k miles, zero appreciable oil burn, no coolant loss, and DT40 oil changes every 6 months.

 

@escreation Sorry I missed this post, must have been a lot of posts at the time and it got burried quickly..

I but I think you are talking about the over-pressure dump valve on the bank 2 breather hose connector that is used on the 996.1 cars....They tend to leak oil even on high mileage non-Supercharged cars..The 996.2 cars don't have these and I recommend that they be capped/plugged off..

Also I would recommend that you test the blow-by on your engine to see how Liters Per Minute of blow-by your engine has..



That orangy-brownish residue is the water vapor condensation reacting with the oil vapors and additives..Same as the stuff that is sometimes found in the oil fill tube under the oil cap...Just clean it off, it does no harm..

 

Interesting,,, never thought of how the AOS system would work on a boosted m96..?

With basically no substantial vacuum ever on the AOS diaphragm, instead it seeing positive pressure majority of time of maybe 10psi or more ?, how can aos open to vent the crankcase...?
Whats the best way to vent a boosted engine's crankcase...?

 

Supercharged or Turbocharged engines pressurize the Intake System under moderate to heavy acceleration so considerations have to be made.....The Intake to AOS connection has to be blocked/and diverted under these cirumstances ( EPA Legal) or the set up has to have the Crankcase Ventallation /AOS routed to the air cleaner instead of the Intake ( not EPA Legal) ....

Either way the "Boosted" engine will increase torque which will increase blow-by and will need a more efficient AOS system like the UAOS System to keep from over-whelming the system for maximum performance...
